Abstract

The Praseodymium (Pr) inserted gate AlGaAs/InGaAs heterostructure doped-channel field effect transistors (DCFETs) exhibit improved dc and rf power performance, as compared with the conventional ones, resulting from the gate leakage current reduction. The Schottky gate breakdown voltage enhances from 8V to 15V, and a power-added efficiency (PAE) improves from 38% to 43% at 1.8 GHz.
